Composite organic filaments

Abstract

A composite organic filament comprises an organic resin matrix and extrafine inorganic fiber-like segments having a diameter of 1 μm or less and uniformly distributed throughout the organic resin filament matrix. The composite filament has a diameter of 3 to 500 μm, and the fiber-like segments comprise carbon fibers produced by a vapor phase growth process and potassium titanate whiskers.

I claim: 
     
       1. A composite organic filament comprising an organic resin matrix and 2 to 70 wt. % of extrafine fiber-like segments uniformly distributed throughout the organic resin matrix, wherein said extrafine fiber-like segments comprise carbon fibers produced by a vapor phase growth process, said carbon fibers having a diameter of from 0.1 to 1.0 micrometers and a length of from 3 to 500 micrometers and wherein said composite organic filament is produced by spinning said filament. 
     
     
       2. A composite organic filament according to claim 1, wherein said fibers are present at a content of 10 to 50 wt %. 
     
     
       3. A composite organic filament according to claim 1 wherein said filament has a diameter of 4 to 100 micrometers. 
     
     
       4. A composite organic filament according to claim 1, wherein said extrafine fiber-like segments comprise said carbon fibers and potassium titanate whiskers. 
     
     
       5. A composite organic filament according to claim 4, wherein said whiskers are present at a content of 10 to 50 wt %.
